Definitions

  • the invention relates to a self-propelled sweeper, comprising a chassis, a passenger area, which is arranged on the chassis, at least one roller brush and a dirt collection container device, which is arranged movably to the chassis via a holding device, the dirt collection container device having at least a first position and a second position to the chassis, and wherein during operation of the sweeper in the first position, sweepings are fed through the at least one brush roller to the dirt collection container device and in the second position it is possible for the dirt collection container device to be emptied.
  • the invention also relates to a method for manufacturing a sweeping machine.
  • EP 3 205 251 A1 discloses an industrial floor sweeper.
  • DE 1 220 455 discloses a self-receiving sweeping machine which is detachably linked to the pivotable boom of a front loader and can be exchanged for other devices.
  • a floor cleaning machine comprising a chassis, a suction bar device which is attached to the chassis frame, a dirt receptacle, and a holding device which holds the dirt receptacle movably relative to the chassis, the dirt receptacle having a dirt receiving position and a dirt release position via the retaining device, and in the dirt release position the dirt receptacle in positioned at a height distance transverse to a longitudinal axis of the chassis at a distance parallel to the longitudinal axis of the chassis relative to the dirt pick-up position.
  • US 3,744,653 discloses a mobile lever suction apparatus.
  • US 5,193,382 discloses a mechanism for lifting and pivoting a container for emptying.
  • WO 2006/121783 A1 discloses a scrubbing machine.
  • the FR. 2 255 841 A1 discloses an agricultural machine.
  • the invention is based on the object of providing a sweeping machine of the type mentioned at the outset, which can be operated in a simple and safe manner.
  • this object is achieved according to the invention in that the holding device and/or the dirt collection container device has a window which, in the second position of the dirt collection container device, provides an operator who is correctly positioned in the passenger area with a see-through field of vision.
  • the field of vision can be restricted for an operator in the second position of the dirt collection container device. This makes shunting for high emptying, for example, more difficult. sample For emptying into a container, the dirt collection container device must be brought into the second position and only then can the container be approached.
  • a window is provided which provides the operator, who is positioned in the passenger area, with a see-through field of vision. This makes maneuvering easier and, in particular, it is also possible to drive up to a container for elevated emptying without outside help and without cameras and the like having to be provided.
  • the high emptying can also be observed through the window.
  • the second position can be a single position of the dirt collecting container device for high emptying, or several second positions can be provided, in each of which high emptying is possible.
  • the chassis has a first end and a second end, with the dirt collection container device being arranged in the region of the second end, and if the see-through field of vision is arranged and designed in such a way that in the second position of the dirt collection container device there is a view through through the window in a direction from the first end to the second end.
  • an operator can observe the high emptying.
  • the arrangement of the dirt collection container device in the area of the second end means that, particularly in the first position of the dirt collection container device, the dirt collection container device is arranged between the passenger area and the second end.
  • the chassis has a first end and a second end, with the dirt collection container device being arranged in the area of the second end, and that the sweeper is assigned a maneuvering area which lies in front of the second end, with the second end between the and wherein an operator properly positioned at the passenger area has a see-through field of view through the window of at least one of: the maneuvering area; onto a floor area in front of the second end; on a projection of a closure of the dirt collection container device onto a floor on which the sweeper stands; to an openable closure of the dirt collection container device.
  • the dirt collection container device when the dirt collection container device is in the second position, it can maneuver precisely and approach an emptying container. In particular, he is then not dependent on outside help. Furthermore, if an operator has a clear field of view of the closure, he can position it specifically on a container, for example, in order to carry out an optimized emptying process.
  • the window is delimited by struts of the holding device; the window is bounded by the dirt collection bin means; the window is delimited by a body which is arranged on the chassis; a highest point of the body does not protrude beyond a seat arranged at the passenger area; the window has a material-free area; the window is at least approximately square or rectangular in shape; the window has a width of at least 50 cm and for example a width of the order of 80 cm; the window has a height of at least 40 cm and for example a height of the order of 60 cm; the window has an area which, in the second position of the dirt collection container device, is at the same height above a floor on which the sweeper stands, as a closure of the dirt collection container device.
  • a see-through field of vision can be easily implemented on the sweeper. Because the window is delimited by the dirt collection container device, an operator can also observe an emptying process, for example. The formation of the window as a material-free area results in less construction effort.
  • a sufficient see-through field of view can be provided by a sufficient size, in particular with a width of at least 50 cm and a height of at least 40 cm. The fact that the window is at least partially at the same height as the closure results in optimized positioning and an emptying process can be observed.
  • the holding device is arranged so that it can pivot relative to the chassis, in particular with at least one of the following: a pivot axis of the holding device is parallel to a wheel axis; the pivot axis of the holding device is parallel to an axis of rotation of the at least one brush roller; the pivot axis of the holding device is transverse and in particular perpendicular to a longitudinal axis of the chassis; in the second position of the dirt collecting container device, this is spaced apart from the first position in a vertical direction of the chassis, and the pivot axis of the holding device is oriented transversely and in particular perpendicularly to the vertical direction; a drive for positioning the dirt collection container device.

  • the filter device has a clean side, which faces the suction unit device, and has a dirty side, which faces the dirt collection container device.
  • the suction flow impinges on an interior space of the dirt collecting container device. In this way, the coupling of sweepings from the at least one brush roller into the dirt collection container device can be assisted and the impact of dust on the sweeping machine and the environment can be minimized during a sweeping process. It is favorable here if the dirt collection container device has at least one connection for the suction flow, which is fluidly connected to the suction unit device, with the at least one connection being at a distance from an opening, in particular in a vertical direction (relative to the direction of gravity), through which sweepings are discharged into the Dirt collection device is coupled.

  • the filter holder is designed as a filter box or is arranged on/in a filter box. It can be done in a simple way Way to accommodate a filter device such as a round filter.
  • the filter box can also accommodate the suction unit device. As a result, torque can be coupled to a motor in an interior of the sweeping machine in a simple manner.
  • the filter holder and possibly also the suction unit device can be brought into a “non-obstructive” position in a simple manner.
  • the filter box can be used as an openable cover for an interior of the sweeper.
